Sophia Electric 6SN7 tube does not look like a typical 6SN7. By looking at the internal plate structure, it is more of a European tube structure rather than North American 6SN7. However the vintage European ECC32/33, CV181/CV1988 family of tubes are not real 6SN7 tubes. What is the story? Sophia Electric designers were smart enough to take European virtue combined with North American 6SN7 electrical tube characters, further Added with 1920's brass base accent. This is how these ST shape Sophia Electric 6SN7 tubes were born!
Sophia Electric 6SN7 would sound with a lot of more openness, more clarity and less distortion than the very best from vintage time. It just sounds bigger(better high frequency extension), louder (more drive voltage swing output), more 3-D imaging for sure (due to better testing and matching procedure applied in any tube amplifier and pre-amplifier). Hundreds of users reported Sophia Electric 6SN7 tubes are better than the vintage 6SN7 tubes being replaced, even the best from vintage time.
